To all whom it may concern:

Be it new that I, Cnannns A. ROBIN- soN, a citizen of the United States, residing at Beacon, in the countyof Dutchess and State of New York, have invented a certain new and useful Fur-Mixed Felt, of which the following is a specification. I

This invention relates to the production of a furmixed felt, particularly for use in the manufacture of hats and caps although well adapted for piece goods and forinany other purposes y Attempts have heretofore been made to produce a fur mixed felt spreading loose, that is to say uncarded or unformed, wools and furs upon a floor in layers, first a layer of wool, then a layer of fur, another layer of wool, and so on. This loose material was then run through a mixing orfwillowing machine from which it was blown into an inclosed chamben From this chamber it was taken and run through a carding machine, after whichthecarded stock formed was felted and finished in the usual manner, by dyeing, hardening, sizing, pouncing, and finishing, as required.

The fur mixed felt produced by this process was so unsatisfactory that it proved a commercial failure. In the first place, it was found that as the wool and fur, more or less mixed therein, were discharged from the willowing machine a large part of the fur, which is lighter than wool, would rise to the top of the chamber and then settle down upon the wool in layers, in practically the same unmixed condition as before going through the machine; and consequently, when fed into the carding machine, the wool and fur would be in lumps so that it could neither be mixed thoroughly nor evenly, and while being carded the fur would be loosened and fly out so that much of it was lost. Again, this carded stock could not be dyed evenly, nor could a uniform color be obtained by dyeing the wool and fur before attempting to card them. Further, the carded stock, because the fur and wool were not well mixed, could not be properly felted, and it was impossible to give the felt a uniform sizing since wool requires a much stronger sizing solution than does fur. And, when pounced and finished, the felt had an uneven or pitted appearance and would not stand the stretch- FUR-MlXED FELT.

ing, blocking, and shaping required for bats, caps, and many other forms. In short, the results were so unsatisfactory that hatters and fe1t makers generally have pronounced the making of a commercial fur mixed felt impossible.

By my present invention I have succeeded in overcoming the above mentioned defects and, for the first time so far as I am aware, have produced a fur mixed felt in which the fur is thoroughly and evenly mixed througlr out the wool, without loss, and which can be closely felted, will dye level, can be stretched and formed into cones and flat plateaus for hats and caps or into other forms, can beuniformly sized, and can be pounced and finished so that it has substantially the appearance of and feels like a pure fur felt; i

The process by which I have produced this new article of manufacture, a fur mixed felt in which a layer or body of fur is thorouglily and evenly mixed into and through an adjacent layer orbody ofwool, consists, broadly stated, in first placing a bat of fur upon a hat, or preferably between two bats, of carded wool. stock and then carding the composite bat thus formed, after which the mixed stock can be felted by vibration or in any suitable manner and then sized, pounced. and finished in the usual way.

The invention will be understood by reference to the accompanying drawings, forming a part of this specification, in which Figure 1 is a side or edge view of a short length of a bat of carded wool stock; Fig. 2, a similar view of a fur bat; Fig. 8, a similar view of a composite bat, formed by placing a fur bat between two wool bats; Fig. 4, a similar view of the composite bat shown in Fig. 3 after the same has been carded; and Fig. 5, a similar view after the mixed felt stock shown in Fig. 4 has been reduced and hardened by vibration.

As therein illustrated, the numeral 6 indicates bats of carded wool stock, of uniform thickness, which are or may be formed upon a carding machine, and 7 indicates a bat of fur, also of uniform thickness, which is formed in any suitable manner, as for example by running a weighed amount of fur through a fur-blowing or forming machine onto a perforated forming pan. The bats having been prepared, a bat of fur is laid upon a wool bat and for the purpose of confining the fur, a second hat of wool, which. need only be thick enough for the purpose or may be omitted altogether, is preferably laid upon the fur hat. The composite bat thus formed is then carded, by running it through the usual carding machine or in any other suitable manner, and thereby the fur 1n the layer or body of fur is thoroughlyworked into and through the adjacent layer or layers of wool, forming a web 8 in which the fur and wool are evenly .and thoroughly mixed. This mixed stock web, which as'it leaves the carding machine may be formed into cones flat plateaus, or other. shapes for hats or caps or may be taken from the carding machine in a flat web if'intended for piece goods, is then reducedand hardened into felt 9 by vibration, for example, upon a vibrating machine or jigger. The stock may be dyed either after the bats have been formed and before the composite bat is carded or after the mixed felt web hasbcen hardened, and in either case will take the dye evenly. The felting process may then be completed in the usual manner, by sizing the hardened felt on a sizing machine or falling it in a fulling mill and then running it through a sizing ortwisting machine, and

linally by pouncing and finishing as usual.

The finished product is a fur mlxed felt .in which the fur is evenly and thoroughly distributed throughout the wool and which, consequently, hasbeen dyed level, is properly felted in the shape required and uniformly sized, and closely approximates a pure fur felt in appearance and texture;

While I have specifically illustrated and described my invention in what I now consider the best mode in which to put it into practical use, it will be understood that it can be variously modified in its several details, by the substitution of equivalents and otherwise, without departing from the spirit or sacrificing the advantages thereof.

lVhat I claim as new, and desire to secure by Letters Patent, is V 1. A fur mixed felt of substantially uniform composition throughout formed by placing apreviously formed bat of furupon a bat of wool and working the composite bat thus formed to thoroughly mix the two materials.

2. A fur mixed felt of substantially uniform composition throughout formed by placing a hat of fur between two bats of wool and working the composite bat thus formed to thoroughly mix the furand wool.

3. A fur mixed felt formed by carding a composite bat made up of a previously formedbat of fur and one or more bats of wool. V

l. A fur mixed felt of substantially lllll. form composition throughout formed by carding a composite bat made up of a hat of fur placed between two-batsof wool.
